'RAILWAY-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 717,603, dated January 6, 1903.

Application 'nea Aprn 2s, 1902.

To all whom, it Wto/y con/067%:

Be it known that I, JOHN F. OCONNOR, a citizen of the United States,residingat Easton, county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Railway-Car Trucks, of which the following is a speeication.

This invention relates to improvements in that class of railway-car trucks which are xo provided with a pivoted jaw which can be swung outward and upward for the purpose of removing the journal-box horizontally from the truck in the direction of the rails through the opening formed by swinging upward said Jaw.

The objects of my invention are to simplify the construction of the parts of the truck, to strengthen the same, and to give the truck greater clearance between its lowest parts zo and the rail, and also to give the lower corners a finish, so that they will not be apt to catch on the road-bed, cross-rods, switch-rods, rbc., in case of derailrnent.

In the accompanying drawings, in which 2 5 like letters of reference indicate like parts in all the figures, Figure l is a side elevation of my improved truck, parts being in section and others omitted. Fig. 2 is a plan View of the reinforcing-casting, parts of the hinged 3o jawbeingin section. Fig. 3 isavertical transverse sectional view showing the hinged jaw.

Fig. 4 is a side View of the hinged jaw. Fig.

5 is a horizontal sectional view on the line 5 5 of Fig. 4.

The sides of the truck are formed of I- beams A, which are split and spread upward and downward at their ends, so as to form an opening for receiving the springs and journal-box, as shown on the left-hand end of 4o Fig. 1.

On the outer surface of each I-beaul A and at each end thereof a U-shaped malleableiron casting or reinforcing-frame B is riveted, the inner leg B' of which is longer than the outer legB2, and said inner leg extends from the upper surface of the bottom iiange of the I-beamA, at the split and spread end thereof, to the under surface of the 1top flange. This casting B has a ange h aiong its inner edge,

5o and at the top this fiange is widened out to form a circular seat O for the upper end of Serial No. 104,240. (No model.)

the bearing-spring C', said seat having a recess for receiving the upper end of the spring.

On each face of the casting B a curved wing D extends from diainetrically opposite points 5 5 of said circular seat C downward and inward at an angle of about forty-tive degrees at the flange b for the purpose of strengthening and reinforcing the upper inner corner of the casting,i which corner is subjected to great 6o strain. The wings D connect. at their upper ends with the circular spring-seat on a transverse or diametrical line through said springseat, iocked midway between. the front and rear legs of said U-shaped frame.

A vlatch E is pivoted at its upper end to the shorter outer lleg B?" of the U-shaped casting B by a bolt V and is provided on its inner edge with a ange of the same size as the Hange b on the longer leg B". At its outer 7o edge the latch E is provided with a narrower flan ge c on each side. The iian ge e of the latch is gradually widened out at a point a short distance above its lower end and is curved downward and inward to form a runner F, the lower inner end of which terminates in an arm G, which seats against the under side of the ange ct of the split and spread I-beam. Above this flange part of the web remains, forming a ridge a2, at the outer end of which 8o a portion of the web forms a spur d3, projecting slightly above the flange d2 and having its upper edge inclined downward and outward. The latch E is provided at the bottom of its inner edge and directly above the arm G with a socket E' for receiving the iiange ct' and with a recess E2 for receiving the spur c3. At each side of this recess E2 a boltsocket E3 is formed, the outer face of which is iush'with the inner iiange of the latch, and go each bolt socket is provided with a hole through which a bolt can be passed. At the free end of the arm G on the latchE a recess H, open at the bottom, is formed at eachside of the longitudinal central web, and in the top of said recess a bolt-hole is formed,through which a bolt can be passed. f

On the upper surface of the bottom flange d of the split end of the I-heam a casting L is secured, which has a longitudinal hollow Ioo central ridge for receiving the ridge a2 on the flange 0.', and this casting has two laterallyextending wings J, which rest upon the upper surface of the bottom fiange a. Two rivets J are passed through said wings J of the casting and through the bottom flange of the split end of the I-beam, and in advance of each rivet a bolt-hole is formed in each wing J, through which a bolt M can be passed, which bolt also passes through the corresponding hole in the recess I-I of the arm G on the latch E when said latch is in a closed position. At the outer end of said casting J a transverse wall J2 is formed in line with the rear end of the spur a3, which wall has a bolthole at each side of the hollow ridge that receives the ridge a2. When the journal-box has been placed into the proper opening in the truck, the latch E is swung down, its arm G resting against the under side of the flange a and the lower part of the inner flange e of said latch resting against the transverse end wall J2 of the casting J. Two bolts S are then passed through the corresponding holes in the bolt-sockets E3 on the latch. Nuts are screwed on the outer ends of these bolts. Two bolts M are passed through the holes in the wings of the casting J and through the correspondingr holes in the arm G of the latch E, and on the lower projecting ends of these bolts nuts are screwed. A bolt T is then passed through corresponding holes in the forked upper hinged end ofthelatch andin the short leg B2 of the casting B and in the split in? of the beam and a nut screwed on said It will be observed that the lower ends of the bolts M are contained within the recess H, formed at the inner end and under side of the arm at the bottom of the latch and do not project sufticiently to catch on anything and can ride over sleepers, switch-rods, duc., in case of der-ailment without catching on them. In case of a derailment, the rounded and wide shoe F behind the outerends of the bolts S and the nuts thereon are concealed, and can run and slide over sleepers, ties, and switch-rods, and the like without digging into them or catching on them. This shoe or runner not only protects the truck from damage in case of derailment, but also prevents the truck from catching on the track and causing a pile-up.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, iS*- 1.
